Required Materials:

Arduino board

9 switches

18 LEDs (9 of each color)

18 resistors (We used 330)

2 small bread boards

1 large bread board

Lots of Wire

Step 1: Setting Up the Bread Boards

Connect the bread boards by whatever means, we had to use hot glue to hold the two smaller bread boards to the larger one. Put the LEDs in the bread boards forming a 3 x 3 square with one of each colored LED in each segment of the square.

Step 2: Wiring

Place each of the resistors after the LED in their circuit. Run wires from the player controlled switches to the LEDs that you want the player to be controlling. Run wires from the same place as in the previous step and hook them up to the Arduino. Run wires from the opposite side of the switches to the positive strip on either the right or left side of the bread board. Run wires from the LEDs to the negative strips nearest them so that they all circulate into one strip then run one wire from the combined strip to the ground (gnd) on the Arduino. Run wires from the computer controlled lights to the Digital and Analog inputs on the Arduino board. Try and keep all the wires as low as possible or the second picture above may be how this turns out for you.

<p>hello, nice job, do you have a electric schematic to send me please?</p>
Sorry I do not it was done at a camp over a weekend a while back and I don't think I have any files from that camp left over. Sorry again that I couldn't be of any help
<p>Hi, what could I change in the code if I want to use an FSR instead of a switch.</p>
<p>Impressive fritzing work! Updates of classic games can never have enough LEDs.</p>
